Step 1: First Row

#### Problem 1:
$$
778473 + 313004
$$
- Align the numbers by place value:
$$
\begin{array}{r}
778473 \\
+ 313004 \\
\hline
\end{array}
$$
- Add column by column from right to left:
- Units: \(3 + 4 = 7\)
- Tens: \(7 + 0 = 7\)
- Hundreds: \(4 + 0 = 4\)
- Thousands: \(8 + 3 = 11\) (write down 1, carry over 1)
- Ten-thousands: \(7 + 1 + 1 = 9\)
- Hundred-thousands: \(7 + 3 = 10\) (write down 0, carry over 1)
- Millions: \(0 + 1 = 1\)

Result:
$$
778473 + 313004 = 1091477
